Vorschrift

To a three neck flask fitted with a mechanical stirrer, a thermometer, and a condenser, is added 124 g (1 mole) of 4-fluorobenzaldehyde, 89.1 g (1 mole) of 2-(N-ethylamino)ethanol, 138.2 g (1 mole) of anhydrous potassium carbonate, and dimethylsulfoxide. The mixture is heated at 95° C. for 3 hours. After cooling to room temperature, the solution is poured into a four-fold excess of ice water, and the solid product is collected by filtration and recrystallized from water.
